POLE-B ASE.

Specification of Letters Patent.

Patented Sept. 3, 1907.

Application filed December 27,1906. SerialNo- 349.632.

To all whom it may concern:

Be it known that I, MAURICE HENRY MURRAY, of Bakersfield, Kern county,California, have invented a -new and Improved Pole-Base, of which thefollowing portion beneath the ground.

The object of my invention is to produce a simple, comparatively cheapreinforced concrete base which can be easily planted in the ground, andto which a pole or post can be conveniently and securely attached sothat the life of the'post or pole is rendered extremely long and economyis thus conserved.

Another object of my invention is to produce a de- 1 vice of thischaracter which can be applied to existing lines of telegraph,telephone, or other poles, so that the bases can be planted, the polescut oil at the ground, and the poles then placed in position upon thebases and securely fastened.

With these ends in view, my invention consists of a pole or post base,the constructionol which will be hereinafter described and the novelfeatures claimed.

Reference is to be had to the accompanying drawings forming a part ofthis specification, in which similar figures of reference indicatecorresponding parts in all the views.

Figure 1 is a broken side clevation, partly in vertical section, oi apole base and attached pole showing my improvement. Fig. 2 is a crosssection on the line 2.2 of Fig. 1. Fig. 3 is a view similar to Fig. 1,butshow ing a modification of the invention, and Fig. 4 is a crosssection on the line 4.4 of Fig. 3.

The preferred form of structure is shown in Figs. '1 and 2, as this isadapted to be applied to existing lines or to poles already erected. Asshown, the base '10 which is of concrete, is reinforced by the metallicstraps 1], which are of a general U shape, and cross each other at thebottom as shown at 12, the crossing parts being n-efombly fastenedtogether as by rivets 13. The upper ends of the straps are connected bycross bolts 15, and it will be observed that the stmps and the bolts arewholly embedded in the concrete, and this can be conveniently done inthe usual manner by placing the par-ts in the mold and pouring theconcrete-around them. The ends of the straps 11 terminate in flanges orlugs16, which are adapted to abut with corresponding lugs 17 on thestraps 19, and the meeting lugs can be secured by bolts 18, orequivalent fastenings. The

a bolt holes are oblong as shown in Fig. 2 so that the structure can beadjusted to poles of different sizes. The

straps 19 extend upward sufficiently high to securely brace thepolc orpost 20, which is placed between the straps, and cross bolts 21 extendthrough the pole and through the straps, and thus'make a secureconnection between the pole and the base 10. It will of course beunderstood that the pole and base can be of any approved cross sectionalshape, and it will further be understood that the joints of theconnecting straps 1]. and 19 can bemade all around the structure asdescribed,

or these joints can occur only on a few of the straps, one 5 5 or more,and the others leit long as in Fig. 3.

In Fig. 3 I have shown a structure similar to Fig. except that the base10 has its straps 22 and 22 which are embedded therein at right anglesto each other,

made long enough to extend well above the base,

where they can bc secured to the pole or post substantially as alreadydescribed, by the cross bolts 21. The straps 22 are arranged in pairs,and one pair is considerably longer than the other as the drawing shows,so

that the strain will. be distributed well through the base, and the endsof the straps are preferably turned" in as at 23, and the straps areconnected by cross bolts 24, which are embedded in the concrete.

1t will be seen that in oithcrcase I produce a "very simple andsulistantial concrete base, and that the base is one which can be easilyapplied either to new lines or to posts or poles which. have beenalready crcctod. It will be noticed that the base of my invention hasthe metallic parts securely anchored, and that they are arranged so thatthe strain is well distributed, and further that the said metallic partsat the points which are to be below ground, are wholly embedded in theconcrete or cement so that such paris'wil] not rust.

Having thus l'ully described my invention, I claim as new and desire tosecure by Letters Petunial. A device of the kind described. comprising:1 concrete hnse having longitudinally reinforcing straps therein, thestraps being arranged in opposed pairs, with the pairs of straps atangles to each other and with the bottoms ol' the pairs connecting andcrossing. the ends of the straps being cxlcndcil from the base forattachment to a super-strumurc.

2. A device of the hind described, comprising a concrete base havinglongitudinally arranged straps embedded there in, with their upper endsonly exposed 1d a second series .ol' straps adopted to connect to thellrst series and constructed also for attachment to u post or polo.

25. A device of the kind described, comprising a concrete base lmvinglongitudinully arranged metallic sir-nus wholly embedded therein exceptat their extreme upper ends, transverse anchoring means for the strapsarranged near the tops of the straps, and a second so of straps havingmoans-for attachment to a pole, and having flanges to abut with theflanges of the first series of straps.

MAURICE HENRY MURRAY.
